==Power Supply interface ==

=== Description ===

The Power Supply interface available on the Evaluation Kit at can be provided through the J1 connector ''TBD:Jxxx''. Power voltage range is +[12-24 V].

''Jxx'' J1 is a ''TBD:connectortwo pins MSTBA 2.5/2-G-type'' header 5.08 Phoenix connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).

=== Device mapping Power LED ===UART3 DL1 is mapped to <code>/dev/ttymxc2</code> device in Linux. The peripheral is used as a green LED (placed near the default serial console, both for SOM) it shows the bootloader and status of the kernelpower input. === Device usage === To connect to the debug serial port: # connect the DB9 adapter bracket to the J22 connector on the SBCX board# connect This LED is ON when a serial cable between DB9 connector and PC COM valid power supply is present either from J1 or USB OTG port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1.
